Morning All,

This morning I was trying to change some of the memory contents on my Baofeng UV-B5 using the latest Mac OS version of CHRIP.

Downloading the existing memory contents into the computer works just fine, therefore confirming that the computer / software / serial interface is seeing the radio OK. However
when I try to upload the memory file back into the Baofeng the transfer fails. I get the following error reported,

"An error has occurred Radio did not ack programming mode."

I have tired upload the original memory contents file I downloaded from the radio a few seconds earlier, without alteration, and the upload still fails.

When I tried the same experiment using Parallels (a PC emulator for the Mac running Windows 7) everything worked just fine, both the download and the upload worked
as expected without errors.

So it would appear that there is something of an issue with the Mac version and uploading to the radio which does't exist on the Windows version.

Hope that this helps,

Have you been able to resolve this on your own since you submitted this?
Have you tried with a recent version since you submitted this?

This looks like a cable issue. Please refer to these Wiki articles:
CableGuide FTDI OEM Cables
RTSystemsCablesAndMavericks (if you're running MacOS)

If there's no solution to be found in any of them, please read: How To Report Issues and provide a debug log. Thank you!

MacOS: this OS is apparently very picky about USB to Serial cables. From what I heard, only (genuine) FTDI-based cables can be made work.
You must have the KK7DS Python runtime for Mac OSX installed.
